PIPE-COUPLING MACHINE.

Specification of Letters Patent.

Patented Feb. 3, 191%.

Application filed January 6. 1913. Serial No. M0391.

To (17/ trim/u it may (oh-worn .ie it.v known that l. linxns'iI'TUMPHREY, a citizen of the l nited States. residing in the city andcounty oi? Denver and State of tol ratto. have invented certain new anduset'ul ltnproveinents in Pipe-(oupling Machines: and l do declare thefollowing to he a full. clear. and exact description of the. invention.such as will enable others skilled in tl" art to which it appertains tomake and use the same. referen e. being had to the avcompanyingdrawings. and to the tigg ures ol retort-n e marked thereon. \vhit'h lt-i part of this specification.

My invention relates to improvements in pipe eoupliu;- nutehiuc. andconsists in lt2tttl!:- l'or making such couplings by formngiuterengagying heads upon the ends of the pipes to he joined. thusmaking a fluidtin'htjoint \vithout: rivets.

()ne object of the invention is to provide a nutchine which shall beadapted to different lengths and diameters of pipe sections.

Another object of the invention is to pro \ide means, for rotating thepipes during the joining operation.

Still another object of the invention -is to provide means for readilyand quickly throwing) into and out of operation the pipe turning means.

()thcr objoets will appear hereinafter as l proceed with the descriptiono'l that embodiment of the invention. which, for the purpose oi thepresent application is illustrated in the aceompanyin drawings, iiiwhit-h l*'i;3'ure 1 is a view in side elevation of the entire apparatus.certain other parts being ;-ho\\':=. in section. Fiji. 2 is a detailView partly in set-lion of a portion of the apparatus shown in Fig. '1.the parts being upon a larger scale. Fig. 3 is a fracmental dctuilpartly in cross section. showing: the bead forming elements of myinvention. Fig. :1- is a cross sectio upon the line 4- --l Fig. 1.looking in the direction of the arrows. Fig. 5 a cross section takenupon the line 5 5. l ig. l. and looking in the direction of the arrows.

Raine rct'eroncc charactei's rci'er to like "putts throughout the views.

in the drawings. the numeral 5 indicates a base of any suitablematerial, such, for instance, as concrete or cast; iron. Into the base 5are set bolts 3 by means of which is anchored to the base a standard 7,having a perforation therein adapted to receive a horizontallyprojecting arm 8 shown in the drawing as circular in cross section, the.arm 8 being held in place by means of a out 0 threaded upon a part 10 ofsmall diameter which is integral with the arm 8.

In the forward extremity of the arm 8 is threaded a short rod 11, smoothat 12 to form an axle for a rotatable disk 123 ro- \lt'ltitl around itsperiphery with a head 14. The loosely mounted disk 13 is held in placeupon the shaftv 12 by a nut 15 threaded upon the small tree extremity ofthe rod 11. A second arm 16 mounted upon the standard 7 and projectstherefrom in a direction parallel to the direction of the arm 8 anddirectly above the same. The bracket 17 of a fluid operating hammer 18is secured upon the arm 16 insuch a position as to bring the ope tilingface of the hammer directly above the bead 14, the hammer having agroove 19 cut. therein to cooperate with the head 14 for pipe oininp;purposes in a manner which will be readily understood. The hammer 18 iscontrolled'by a'suitable valve or stopcock 20 and the energizing fluidis fed to the hammer from any suitable source through a riexil'ileconduit 21.

A collar 22, the opening; of which is cocentrieally arranged (as clearlyillustrated in Fig. 5) is mounted to slide upon the arm 8, a set screw2?) being provided for the purpose of fastening the collar in anydesired adjustment, the set screw preventing both longitudinal androtational movements. The collar 22 has formed thereon an annularshoulder 24 against which one end of a pipe section 25 may bear.Antifrietion rollers 26 are mounted Within the collar 22 to facilitatethe rotation of the pipe during the coupling operation. The other sectin 27 of the pipe to be coupled is supported by one or more rings 28 ofsufficiently large diameter to accommodate the largest. sizes of pipes.This ring 28 is formed of material U-shaped in cross section and hasanti-friction rollers 29 mounted therein. it is supported at the top bya short rod 30 and a turn buckle depending from the axle of a groovewheel 32 which rides upon an overhead t ack 33 arranged parallel Withthe arms 8 an. 16'. i

The means illustrated for "ito'tating the pipe section comprises a belt3 255116 ends of which are very readily attached and detached beingconnected by a hinge the pintle 36 of which is removable. The belt 34runs upon the pulley 37, keyed to a shaft 38 which has upon oneextremity a loose pulley 39 and a fixed pulley 40 over either of whichapower transmitting belt 41 may be caused to run by means of a beltshifting lever (not illustrated). Standards 42 and 48 support the shaftjournals 44 and 45 which are of a peculiar construction. ,The

j ournal 44 consists of a sleeve, the outer surface of which is curvedas shown at 46, the 'corresponding 1nner surface of the standard 42being similarly curved so as to/fornif a ball and socket connectionpermitting tilt- Will be readily understood. A collar 22 of the properdiameter is selected and placed upon the arm 8 at a distance from itsroe Ward extremity equal to the length of bne of the pipe sections to bejoined, the. disk 13 being then mounted in place upon the axle 12. Thepipe sections and 27 are then put in place as illustrated in Fig. lofthe drawings, the section 27 being supported in one'ormore rings 28. Abelt 34 of the proper length is then selected and after being passedaround the pipe section 27 and the pulley 3.7 has its ends fastened bythe insertion of the pintle 36 through the parts of 'the hinge 35, itbeing understood that during this belt adjustment operation the hendie48 is in the position illustrated in Figs. 1 and 2, the pulley 37 beingthereby in its highest POSltIOIL The hammer 18 is now started by openingthe stopcock 20 and the belt 34 is rendered taut by throwing down thehandle 48. ,The head ponnection between the pipe sections are then.rapidly formed as will be apparent t2: nyone skilled in the art. lVhenthe joint completed. the sections 25 and 2'? are shifted. to therightbeing supported in the movement by rings 28 and a new pipe section isplaced over the arm 8 and joined to vthe preceding sections in themanner just described.

dis'k loosely rotatable on the noeazwe It will he -apparent that a setof collars 22 of var ous sizes and that a set of belts 34 of variouslengths may be lrept on hand and that by selecting the proper collar 22and belt and positioning the collar 22 in the proper pla; ;""-upon thearm 8 the machine willbe ad'ap able to joining pipe sections of any.length or diameter.

' Delaim as my invention:

1. In a pipe coupling machine, a support including an arm extending intothe pipe for the length of a section approximately, at end of saidsupport, a. mechanically driven rapidly re ciprocating hammercooperating with said disk,0ne of the cooperating elements having a beadand the other a counterpart groove arranged to form intcrengaging beadsupon the sections oi the pipe to be joined.

. 2. in a machine, a standard, an arm fixed in and 'bllojectinghorizontally from said standard, a disk of diameter at least equaltotha't of the arm and carrying abead, said disk being reinovably androtntably sup ported upon the free extremity of the arm, meanscooperating with saidbead for embossing a pipe sect-ion when placed oversaid bead, and a circular disk having eccentrically therethrough anopening adapted to fit-said arm whereby the second named disk isslidable thereon and removable therefrom when the first disk is removed.

3. In a pipe coupling machine, asupport including an. arni extendinginto the pipe for the length of one section approximately, a diskloosely rotatable upon the end of said support, a bead at the peripheryof said dish, a mechanically driven rapidly recipro: eating hammerhaving a groove therein cor responding in shape to said bead andarranged to co-act therewith to form interengaging beads upon thesection of pipe to be joined.

In, testimony whereof I aiilx my signature in presence of two witnesses.
